The Wehrli Custom Fabrication Stage 2 High Flow Bundle Kit for 2011–2016 LML 6.6L Duramax combines a Stage 1 High Flow Bundle and a Stage 2 cold air intake to increase engine airflow and improve throttle response and turbo spool. Fabricated aluminum intake and air box replace restrictive OEM plastic, while large-diameter piping, a cast aluminum turbo intake horn and high-flow intercooler pipes reduce restrictions. Hardware, silicone boots, clamps and components are included and the kit is bolt-on with no tuning required.
